How to Use AI Image Generators

Using AI image generators to create images for your website is a straightforward process. We will use DALL-E as our example AI image generator in this guide.

1. Find a Suitable AI Image Generator Platform

Selecting the appropriate AI image generator platform requires some research. Begin by evaluating the options available in the market. Examine user reviews and industry comparisons critically to identify a platform that aligns with your specific needs and objectives.

When researching and selecting a platform for AI image generation, consider the following factors to ensure that the AI picture generator aligns with your specific needs and expectations:

  • Overall functionality and available features, including API access
  • Quality of the computer-generated imagery
  • Ease of use
  • Cost
  • Quotas and usage limits
  • Response time
  • Reliability and uptime
  • Security and compliance
  • Support and community
  • Scalability
  • Reviews and testimonials
  • Legal and licensing issues
  • Integration options
  • Available trial periods and testing accounts


For instance, if you need realistic images, an artificial intelligence art generator is probably not the best choice. Similarly, concept art-producing AI won’t be helpful for users requiring visual effects on existing images.

Consider the necessity of Application Programming Interface (API) access in your decision, too.

An API allows seamless integration of the AI image generator into your existing workflow, automating the AI image generation process.

API access is useful for fast experimentation, cost-effective bulk image creation, and generating images when not physically on the AI platform itself.

Most reputable AI image generator platforms allow users to register for API access. This registration typically involves creating an account with the platform and generating a unique API key. This key is critical as it authenticates your access, allowing secure interaction with the platform’s API when creating images.

To gain access to DALL-E’s API, users are required to register with OpenAI. Follow these steps:

  • Go to the OpenAI website.
  • Click on the Product menu and select DALL-E 2.
DALL-E homepage
  • Click on the Try DALL-E 2 button.
  • Sign in to your OpenAI account or create a new account. If you’re creating a new account, agree to the terms of service and privacy policy and select a plan.
OpenAI create an account popup
  • Select DALL-E to use the browser version of the AI generator, or select API to set up OpenAI with your application.
OpenAI selection screen
  • In the API Overview view, select your profile and choose View API keys.
OpenAI API homepage
  • Follow the instructions on the page for creating an API key. For more information, read the API reference guide.
  • You can now start using the DALL-E API in your applications.

Once you have an account and an API key, it’s time to start generating images:

  • Import the OpenAI Python client library:
import openai
  • Import module for opening and reading URLs:
import urllib.request
  • Set your API key:
openai.api_key = "YOUR_API_KEY"
  • Create a prompt:
prompt = "A cat sitting on a stack of books"
  • Generate an image:
response = openai.Image.create(prompt=prompt, width=1024, height=1024)
  • Get the image URL:
image_url = response.url
  • Save the image:
urllib.request.urlretrieve(image_url, "image.jpg")

Here is an example of how to make an API request for DALL-E in Python:

import openai
import urllib.request
openai.api_key = "YOUR_API_KEY"
prompt = "A cat sitting on a stack of books"
response = openai.Image.create(prompt=prompt, width=1024, height=1024)
image_url = response.url
urllib.request.urlretrieve(image_url, "image.jpg")

2. Prepare Image Prompts for Image Generation

Understanding the input format for the chosen AI image generator is important, as this varies between different AI image generators. Generally, the input required consists of a text prompt. This prompt could be a full sentence, a list of keywords, or a combination of the two.

For best results, write clear and descriptive prompts. Specificity in the text input often results in more accurate and relevant image outputs, making the entire process smoother overall. Consider both conceptual prompts, which outline the content of the generated image, and stylistic prompts, which suggest a desired color scheme or art style.

Descriptive and Clear Prompts:

  • A golden retriever puppy playing in a field of sunflowers
  • A futuristic city skyline at sunset with flying cars
  • A serene beach scene with a family building a sandcastle

These prompts are detailed and paint a vivid picture of what the user wants the AI image generator to produce.

Conceptual Prompts:

  • A scientist examining a DNA strand in a laboratory
  • An astronaut floating in space, reaching out to a star
  • A bustling 19th-century London street market

Conceptual prompts outline the content or subject matter of the image. They dictate what is in the image, helping to guide the AI in understanding the scene or elements the user wants.

Stylistic Prompts:

  • Rendered in the style of Van Gogh
  • Bright and vibrant color palette
  • Film noir lighting with high contrast

Stylistic prompts suggest how the image should appear, indicating the desired aesthetic, color scheme, lighting, or art style, without necessarily specifying the content of the image.

These examples aim to illustrate the distinction between detailed descriptions for the AI to visualize a scene (descriptive and clear prompts), the subject matter or content of the image (conceptual prompts), and the aesthetic or style in which the image is rendered (stylistic prompts). The creative applications of AI image generators only fully reveal themselves when all of these prompt styles are combined.

3. Generate Images With the AI Image Generator

Making API requests for image generation involves sending a structured request – usually containing the text prompt and desired parameters, such as image resolution – to the platform’s API endpoint.

Typically, the AI platform will respond with either image files, URLs to the generated images, or another form of retrievable content.

To generate images with DALL-E via API requests, follow this step-by-step guide:

Step 1: Install Python

Start by downloading and installing Python:

  • Download Python.
  • Run the installer and follow the on-screen instructions.
  • Make sure to select the Add Python to my PATH environment variable option. This will allow you to run Python commands from the command line.
  • Once Python is installed, you can verify the installation by opening a command prompt and typing the following command:
python --version

Step 2: Install a code editor like Visual Studio Code

Visual code editors are useful for syntax highlighting, autocompletion, and linting. They make writing code more efficient and accurate. Download Visual Studio Code from the official website.

Step 3: Set Up Your Development Environment

Before you make an API request, set up your development environment. This might involve installing necessary libraries or packages. For example, in Python, you might need to install the requests library, which can be done with the following command:

pip install requests

Step 4: Obtain API Key

After registering with OpenAI, generate an API key. This key is used to authenticate your application when making requests to the API. Keep this key secure.

Step 5: Craft Your API Request

In order to run the Python code, create a new file with the name Copy and paste the code into the file.

Next, run the code by opening a terminal window and navigating to the directory where the file is located. Type the following command:


This will run the code in the file and print the output to the terminal window.

To generate an image with DALL-E, you need to craft an HTTP POST request. This request will include several components:

  • The Endpoint URL: The API documentation will provide you with the endpoint URL to which you send your POST request.
  • Headers: Your API key is sent in the headers of your request to authenticate it. Usually, you will have a header for ‘Authorization’ and a header to specify the content type. Example in Python:
headers = {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',
  • Payload/Body: This is where you put the data sent to the API, including your image prompt and any additional parameters (such as desired image resolution). This is often sent in JSON format. Example in Python:
data = {
    'prompt': 'A two-headed pink unicorn',
    'max_tokens': 150

Step 6: Send the API Request

Using the requests library in Python, you can send a POST request like this:

import requests
response ='', headers=headers, json=data)

Step 7: Handle the Response

After you send your request, the API will respond. This response might be a success (often a 200 status code), an error (often a 400 or 500 status code), or something in between.

For a successful request, the response will typically be a JSON object that contains the generated image or a URL where the image can be downloaded. Example in Python:

if response.status_code == 200:
    image_url = response.json()['data']['url']
    print('Generated image URL:', image_url)
    print('Request failed with status code', response.status_code)

Step 8: Use the Generated Image

Once you have the URL from the response, you can download and use the image as per the terms of service.

This is a simplified example, and actual implementations may vary. Always refer to the API documentation of the AI image generator for the most accurate and up-to-date information.

Tips for Generating AI Images

To get the most out of AI image generators, follow the below tips to create high-quality images that are both visually engaging and legally compliant.

Ensure Image Quality and Consistency

Use AI image generators with proven capabilities to produce high-resolution and consistent outputs. Adjusting the aspect ratio, image resolution, and overall output quality ensures that the images created align with your brand’s aesthetic.

For instance, before finalizing your image, compare the output from the AI image generator with your original vision or draft. If you requested a sunset over a serene lake, verify that the colors are vibrant, and the resolution is high. Adjust parameters like aspect ratio in the AI’s settings to match your desired image format, ensuring consistency across all images on your website.

Understand Copyright and Usage Rights

Before using AI-generated visuals for web design or social media posts, understand the copyright implications. Check the terms of service of your chosen AI photo generator; some may allow free use of images generated, while others might require a license or subscription.

Read the service’s terms and conditions carefully if you create images with AI for a marketing campaign, for example. Some platforms might only grant you the right to use AI-generated pictures for personal projects, not commercial ones. Confirm that the tool grants you commercial rights if you intend to use the images in advertisements or product listings.

Enhancing User Experience With AI Images

Regularly updating and refreshing website images is important to keep your website looking fresh. AI image generators help to streamline this process, resulting in improved user experience and better SEO.

Outdated images can make your website look stale and unprofessional and can also contain security vulnerabilities. By regularly updating your images, you can help to keep your website looking its best and protect it from security breaches.

Combine AI-Generated Content With Original Content

AI image generators work by helping with visual content creation, but ideally, you should combine AI image generation with original, human-made content. This way, you can streamline certain aspects of graphic and web design processes without sacrificing or compromising your brand identity.

Consider setting up templates for various recurring marketing materials that require original images, and plan for a human designer for important cornerstone designs, like a complex creative asset.

Use Custom Image Prompts for Specific Results

AI image generators only create images as good as the prompts they are given. Instead of relying on generic inputs, create detailed and descriptive text prompts that specify elements like the scene, objects, emotions, and colors you want to be depicted.

For example, rather than inputting “sunset”, a custom prompt like “a vibrant sunset over a calm ocean, with silhouettes of palm trees in the foreground” provides the AI with a clearer, more detailed guide to follow. This way, you can create an image from text that meets specific needs, whether for a marketing campaign, a digital art project, or social media content.


AI image generators are powerful tools for creating compelling, customized visual content.

Always choose a tool with a proven track record of high-quality image output and good customer reviews. With good prompt engineering, it’s easy to create AI images for your website, social media, marketing campaigns, and more.
